Gross and microscopic changes associated with acute metallic phosphide poisoning in the stomach, liver and heart. a Stomach, grossly there was diffuse congestion of the gastric mucosa, acute erosions in the fundic region and presence of digested blood covering the mucosa; (b) Stomach, diffuse congestion in the submucosa; most blood vessels are polled with red blood cells (H&E stain, original magnification 100X); (c) Stomach, superficial epithelial necrosis with desquamation; a few neutrophils and lymphocytes are visible adjacent to the eroded areas (H&E stain, original magnification 200X); (d) Liver, grossly the organ was congested, friable with multifocal areas of hemorrhage and necrosis; (e) Liver, microvesicular steatosis in the central area, diffusely congested sinusoid capillaries; in the center and in the upper left side of the image, clusters of inflammatory cells are visible (predominantly neutrophils); at the periphery (right side and upper left side of image) a mixture of coagulative necrosis and haemorrhage is observed (H&E stain, original magnification 200X); (f) Liver, central area of acute coagulative necrosis with loss of nuclei surrounded by congestion and haemorrhage (H&E stain, original magnification 200X); (g) Heart, apex, an area of myocardial necrosis and haemorrhage; (h) Heart, myocardial necrosis characterized by homogenization of sarcoplasm with loss of cross striations and micro haemorrhages(H&E stain, original magnification 200X); (i) Heart, fragmentation and loss of myocardial fibers, necrosis of the capillaries walls and haemorrhage (H&E stain, original magnification 400X)
